How much does the 2020 Mercedes-Benz S-Class cost?

Prices have softened 9.93% compared to this time last year, making it a favorable time to shop this model year.

There are 579 listings available, which gives you a modest amount of inventory to compare.

Is the 2020 Mercedes-Benz S-Class a good car?

Yes — the 2020 Mercedes-Benz S-Class earns a 4.9/5 user rating, which points to very strong owner satisfaction. Owners consistently praise its luxurious feel, impressive performance, and advanced features, and the ride comfort is a recurring highlight. The model’s flagship-sedan appeal also fits well if you want a deeply polished luxury car with a strong technology focus and a cabin built for comfort. With 33.9% of listings marked as good or great deals, you have some room to shop selectively.

Is the 2020 Mercedes-Benz S-Class reliable?

Owners rate it 4.9/5, a strong signal of long-term satisfaction.

User feedback also points to a reliable, dependable ownership experience, with owners describing the car as comfortable and advanced while still feeling well put together. That said, used luxury ownership can still bring higher upkeep, so you should expect maintenance costs to matter more than they would on a mainstream sedan.

What should I look for when buying a used 2020 Mercedes-Benz S-Class?

At 71% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle history report and confirm whether any prior damage was repaired properly. Put inspection priority on bodywork, electronics, and signs of uneven wear, since a luxury sedan like this can hide expensive issues if condition is not carefully checked. Focus on overall maintenance history and interior condition, because those details matter a lot on a used flagship car.

Is now a good time to buy a used 2020 Mercedes-Benz S-Class?

This is a moderate market, so you can be selective without expecting every listing to be a bargain.

• Deal availability: 33.9% of listings are priced as good or great deals.
• Inventory: There are 579 listings available.
• Price trend: Prices have softened 9.93% compared with last year.
• Clean inventory: 71.0% of listings are accident-free.

If you find a listing below $46,306, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2020 Mercedes-Benz S-Class's resale value?

The current average of $46,370 sits slightly below last year's $51,479.

That price movement suggests the market has already adjusted downward, which can help you buy more confidently now but may also limit short-term upside if you plan to resell soon. For a future seller, the key is to buy well and keep the car in excellent condition, because luxury sedans tend to reward clean history and strong presentation more than mileage alone. A well-kept example should still appeal to shoppers who want a flagship experience without paying new-car money.

Vehicles with strong owner satisfaction ratings, like this model year's 4.9/5, tend to retain buyer demand, which supports resale value over time.

Should I buy a 2020 Mercedes-Benz S-Class or consider a different year?

If you're weighing the 2020 against nearby model years, here's how to think about it:

Choose the 2020 if:

• 33.9% of listings are priced as good or great deals.
• At 71% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 9.93% compared with last year.
• Owners rate it 4.9/5 — a strong satisfaction signal.

Consider the 2021 if:

• At $58,029, the 2021 costs more than the current year's $46,370 average.
• The redesign brings a more sophisticated infotainment system and updated powertrains.

The 2020 is the better path if you want flagship luxury, strong owner satisfaction, and a lower entry price. If you are more price-sensitive, the 2020 also gives you a clearer value advantage over the newer model year while still delivering the core S-Class experience.
